That seems pretty gross to throw a dead fish in a lake then eat it, right? It seems real gross to me. The fish having lived in the lake and then being eaten is totally fine, but being dead, then in the lake, then eaten hits me as real nasty. I wouldn't eat anything that came from a different location and was placed in a lake. No one was shown eating it as far as I remember, but they were cooking it so let's pretend.
The video was perfect and beautiful in every way though and I'll go buy something.
